For PIC and little associated logic circuit supply I use a drop resistor, zener BZX-C5V1 and ceramic 100nF 50V cap. as a filter. This gives me 5.1V and does not have to be too precise. For 12V I use 2k2 resistor. The PIC is quite happy, and I drive 741 and gate of a MOSFET switch with it.
Cheap and cheerfull, tried and tested on 10-16V.
